Need a SQL query that works, or one that runs too slow? I write clear, tested queries for SQL Server and MySQL.
What I can do:
- Queries with joins, filters, groups and reports
- Optimize slow queries
- Views and stored procedures
- Clean and fix data in your tables
You get the query file, a short note explaining how it works, and one fix round if something doesn't match your data.
Send me your table structure (no private data needed) and the result you want to see.
